I couldn't tell you what the motive for getting your number would be. I am sure it's a scam of some type. More than likely a "I posted it in the wrong area (phone number comes back to Santa Monica CA) western union me the money I will ship it." There is a very slim chance it's someone who moved to MI and kept their number. Lack of information, price, and phone number would make me pass on it not even worth your time to find out more.
